the casing prevent from rotiitni relatively to the eeiiin it ie provided with riidiiilly projecting ri e, e, which engere within i'ertieiil grooves o, a formed in t ie easing. 'l'lie viilve is provided with e'nheiik C' liiiving e right exterior screw thread thereon.

The exterior of the member D iii provided with e left iierew threed which enge ii corresponding iicrew threed formed wit iin the exteniiion l of the viilve eioiiniz.

.'lhe upper portion D' of the member l) is reetiingiiler in croiiii-iiection :ind project within ii iioclret o! similiir erosie-section i-iirried by the vulve stein lil.

llie o .-rution of my invention is iis fiillows: lien il iii desired to iinseiil the viilve the lnieil ilinlt ll 'i riitiileil townril thil left. :inch rotiiry motion being trin niitteil to the member l). 'lhe rotiition ii 'he member l) reletlvely to the eiininf vini-...r ioieh member to move npwerdly whi e iii the .inno time the rotation of liicli ineniliei' relet vely to the vglve lheni C' druwii thi hitte.l npwiirillv v'rlthin the socket in the in mber D. lt will be obeerved that by rcioion o! the reversed eerew threedii, the velve is moved :n.iy from the neet a' both by the npiifird movement of 'the member D reliitively to the casing und b the npwerd inovein'ont of the viilve iihiin relatively to the member l). A coinpiiriitively slight rotiirv motion imparted to the viilve stem consequently results in the viilve being quickly moved iiwey from its seiit.

ln order to clone the vulve the hiind disk lil' iii rotiiteil toward the ri ht lwhich eleets -thefuick eloiiing of the vii ve by reinion of tho i ownwiiril movement of tlm member l) within the ceeing end the coincident downwiird movement of the valve shiink within the iiiieliet o! the member D.

'lhe convex crommeetion o! the vulve sent n' insures e ti ht engagement of the vulve therewith whi e the convex seat b' iigiiinst which the iiniiiiliir thin i i' on the vulve stem is forieil prevent" |iii 'nge of the uid between the viilie sti-ni iinil riniing.

From the forioing diwiiptiini it will be observed tlnit 'l inve invented iin ini roved vulve iiilu ted for mie nii it biiiiiii ooclt, etlcet. giitiuor g obii'iili'e which will iit ell tim be proof iigiiinstleiiknge owing to the eonstent ti ht engagement between the llen on the i'ii t'e stein iind overlying -eiit on t e veli'e eiising. i
